Students should have lockers because it will stop people from stealing their stuff. For example, the children won't have to worry about their books, homework assignments, and personal belongings being stolen. The reason for this is that the children will have their own lockers plus their own locks, which only they have the combination to. This will reduce cases where things are being stolen.
Students also should have lockers so they will have a clean place to put their books. What I mean by this is that many desks are rusty and have gum stuck under them. Also, if you put you stuff into a crate then it is easily collecting dust. This connects to my argument because their stuff will be kept very clean in a neat environment if students are given lockers to use.
My final reason why I think students should have lockers is so students won't complain about caring everything at once. The things that they may be caring everyday are very heavy. This is important because students may suffer health problems from having to carry all their stuff everywhere. Why carry books everyday why you can eliminate the pain by having a locker to store the things you don't need? Also, they're always whining about having to carry all their books. If we had lockers everyone would be happier.
